Radiolink R8FM, 2.4G 8 channels receiver, 2.5 gram weight, S-BUS and PPM signal support, use with Radiolink transmitter T8FB,  excellent choice for racing drones.

 Two Signal Modes:

• Blue/purple LED, S-BUS signal , 8 channels in total.
• Red LED, PPM signal, 8 channels in total.

 Switching S-BUS and PPM Modes:

Quick press the ID SET switch twice within 1 second, the signal is changed from S-BUS to PPM. The red LED indicates the PPM and blue/purple indicates S-BUS.

 Binding:

1. Put the transmitter and the receiver close to each other within 1 meter.
2. Turn on the transmitter, then power on the R8FM.
3. There is a black button on the R8FM, press the binding button twice in two seconds and release, receiver light start blinking, after approx 8 blinks, binding is complete and led remains solid. 

Installation Recommendations:

1.The antenna must be kept as straight as possible. Otherwise it will reduce the effective range.

2.Large model aircraft may of some metal part interfering signal; in this case the antennas should be placed at both sides of the model. Then the best RF signal condition is obtained at any flying attitude.

3.The antennas must be kept away from conductive materials, such as metal and carbon by at least a half inch. The coaxial part of the antennas does not need to follow these guidelines, but do not bend it in a small radius.

4.Keep the antennas away from the motor, ESC, and other noise sources as much as possible.
